CISCO路由器PPPoE实验报告

题目：PPPOE实验 实验拓扑如下： 实验要求： 1.在pppoe-client2路由器上使用NAT，让内部主机能够上网 2.路由器pppoe-client2和pppoe-client1通过pppoe协议拨号连接pppoe-server服务器， 3.在pppoe-server和ISP-router之间使用ospf路由选择协议 实验目的： 掌握1.pppoe在路由器上的配置过程     2.NAT     3.单区域ospf 实验步骤: 1. 使用小凡模拟器搭建实验环境。 2. 2. 在pppoe-server 路由器上配置如下 PPPoe-server(config-if)#username cisco password  cisco 创建一个拨号帐号。 PPPoe-server(config)#vpdn enable    //启用vpdn虚拟私有拨号网络协议 PPPoe-server(config)#vpdn-group adsl0  //创建一个虚拟私有拨号网络组，起名为adsl0                          PPPoe-server(config-vpdn)#accept-dialin  //允许拨入改组 PPPoe-server(config-vpdn-acc-in)#protocol pppoe  //并启用pppoe协议 %Only one PPPoE VPDN group can be configured PPPoe-server(config-vpdn-acc-in)#virtual-template 1  //关联一个虚拟接口 PPPoe-server(config-vpdn-acc-in)#exit PPPoe-server(config-vpdn)#pppoe limit per-mac 10  //限制拨号连接的mac数目为10 PPPoe-server(config)#int f0/0      启用物理接口 PPPoe-server(config-if)#ip add 1.1.1.1 255.255.255.0  配置ip地址 PPPoe-server(config-if)#no shut PPPoe-server(config-if)#pppoe enable  并在该物理接口下启用pppoe协议 PPPoe-server(config-if)#int virtual-template1  配置虚拟接口 PPPoe-server(config-if)#ip address 200.0.0.1 255.255.255.0 PPPoe-server(config-if)#peer default ip address pool ad  指定拨入端的iP池，名字为ad PPPoe-server(config-if)#ppp authentication chap pap callin  启用混合认证方式 PPPoe-server(config-if)#ppp ipcp dns 202.102.128.68 202.102.134.68 给拨入端指派dns PPPoe-server(config-if)#ip local pool vt1 200.0.0.20 200.0.0.254  指定拨入端能够使用的ip范围 PPPoe-server(config)# PPPoe-server(config)#router ospf 10    启用ospf路由选择协议 PPPoe-server(config-router)#net 200.0.0.0 0.0.0.255 area 0  通告直连网络号 PPPoe-server(config-router)#net 100.0.0.0 0.0.0.255 area 0 PPPoe-server(config-router)# pppoe-server(config)#do sho ip rou ospf  查看ospf路由表     5.0.0.0/32 is subnetted, 1 subnets O      5.5.5.5 [110/11] via 100.0.0.2, 00:03:07, FastEthernet1/0 pppoe-server(config)# pppoe-server(config)#do ping 5.5.5.5  测试 Type escape sequence to abort.
